MACHINE FOR APPLYING STRIPS OF PIPING TO SHEEIMATERIAL Filed April 15, 1930 mounted in a carrier which is pivoted about Patented Aug. 18, 1931 UNITED STATES THOMAS PERCY HALL, OF LEICESTER, ENGLAND, .ASSIGNOR "10 UNITED SHOE MA-- PATENT OFFICE OHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY MACHINE FOR APPLYING STRIPS OF PIPING- TO SHEET MATERIAL Application filed April 15, 1930, Serial No. 444,593, and in Great Britain May 15, 1929.

This invention relates to machines for applying to a piece of sheet material a strip of sheet material to provide an ornamental edge and is herein illustrated as embodied in a machine for applying to a leather shoe part an adherent strip of piping in such manner that the edge of the piping extends beyond the edge of the leather.

In the manufacture of shoes it is custom ary in some instances to prepare a strip of piping, commonly made of leather, and usually of a colour diflerent to the main parts of the shoe upper and to apply this strip of piping to a margin of a vamp, quarter or other part of a shoe upper in such manner that one edge of the piping extends beyond the edge of the shoe part so as to be exposed in the finished shoe as an ornament.

To this end there is provided,in accordance with one feature of the invention, a support over which a piece of sheet material is fed,

a guide for engaging the edge of the material, means for directing a strip of piping upon the material with its edge projecting beyond the edge of the material, and means for pressing the piping againstthe material.

In the illustrated machine the piping is directed upon the sheet material at a locality alongside the edge guide considered in the direction of feed movement of the work, and

" a cooperating hammer and anvil act to press the piping against the material and to feed the piping and the material, it being understood that either' the strip of piping or the margin of the sheet material or both have been previously coated with an adhesive.

It is desirable to provide for controlling the extent to which the piping extends beyond the edge of the material and to this end in accordance with another feature of the invention provision is made for relatively adjusting the strip or piping guide and the guide for the edge of the material. In the illustrated machine the strip guide is spring pressed toward the work, and is an axis extending parallel to the direction of feed movement of the work, so that, when the the strip guide is adjusted angularly about its pivot, it remains incontact With the work These and other features of the invention. including certain details of construction and combinations of parts will be described as embodied in an illustrative machine and pointed out in the appended claims. Referring now to the accompanying drawings,

, Fig. 1 is a front elevationof a portion of a machine in which the present invention is embodied;

Fig. 2 is a rear elevation of the same portion of the machine; and

Fig. 3 is an end elevation of part of the same portion of the machine.

The margin of the piece of sheet material, such as a leather shoe part, is fed away from the observer as Viewed in Fig. 1, over a support comprising the top of a block 5 and the top of a plate 7 with its edge in contact with an edge guide 9, there being a lever 11 the lower edge of which is located in a groove in the edge guide 9 and extends over the margin of thesheet material to prevent it from rising. On the farther side of the lever 11 is a strip guide 18 of the shape shown having a substantially horizontal lower portion in the under side of which is a channel 15 (Fig. 2)

through which the piping strippasses. This strip guide 13, is located above and normally rests upon the top surface of the material edge guide 9, but may be raised off the material edge guide during the operation of the machine depending upon the thickness of, the material. A piece of sheet material 100 and a strip of piping 200 are shown in Fig. 3 in process of going through the machine, the strip of piping being led to the strip guide 13 through a substantially upright lead tube 17 attached to a lever 19 which carries the strip guide. On the farther side of the strip guide, as viewed in Fig. 1, is a presser and feed member in the'form of a hammer 21 and an anvil 23, best shownin Fig. 2, which act, as will presently be described, both to press the piping against the material and to feed both the piping and the material.

' The machine has a frame very much like observer to feed the work.

that of the folding machine shown in Letters Patent No. 1,702,598, granted February 19, 1929, upon an application filed in the name of Perley R. Glass, said frame comprising a lower arm 25, which carries the edge guide 9, the hammer 21 and the anvil 23, and an upper arm 27 which carries the other work-engaging parts, Thestem ofthe hammer is pivoted to the stenrof the anvil atz29, and thisstem atits lower end is fast to a horizontal sleeve 31 mounted for rocking movement in a bearing in the lower. a-r1n.25.. The lower end of'the stem of the hammer is pivoted at 33 to a rod 35 whicheXten-ds through the sleeve 31. In the operation of the machine, the rod 35 is pulled to the left (as viewedin Fig 2) to bring the hammer down upon the work. The sleeve 31 is then rocked in a direction to cause the hammer and anvilto swing toward the At the end of the feedfmovement, the rod 35 is moved to the right to cause the hammer to free the work, and then the sleeve 31 is rocked to return the hammerand anvil to the positions shown. Any suitable mechanism may be employed to actuate the rod'35 and the sleeve 31 in the manner which has been described, for excounteract this tendency; This block is mountedat the outer end'of a;small' rockshaft-37 carried (by the lower arm, said fsh-aft; being rocked-atthe proper time to cause the blocki5 to press the workup against the under side of the strip guide 13 andhold it-firmly while the hammer 'andanvil aremoving backward along. the work: This block1and' shaft, togethercwith its operating mechanism (not shown) areor'may b'e substantially like the corresponding partsrshown; in the patented machine;

Thestem offthe strip guide 13' isslidable vertically in a vertical-bore in the outer end ofthe lever-19, said bore having an enlargedfupper portion to receive a spring 3fZf'Which restslat itsilo wer end upon the head oifthe stem, .and' at its upper endengages the bottomlofasorew.39fthreaded into the top of the enlarged portion of the bore; This lever 19-is pivotedat41 between twosmall brackets 43, 1 5,carried {by the. upper arm 27: and has. atiits inner end afingerpieoe 191. The lever 19; (see;Fig,' 2) haspivoted toit'at 1&7 a small upwardly; extending rode9 theupperend of. whiehis threaded .into ashore in the depending portion-.ofia cap 51', saiddepending portion being slidable in a bore formed in apart rigid with the arm 27. A coiled-spring-53 acts to push up the cap 51 and, through the small rod 49, to pull up the rear end of the lever 19 (the left-hand end as viewed in Fig. 2). A stop screw 55, which is threaded through the lever and abuts a stationary part limits the upward movement. With this construction, when the lever 19 is adjusted angularly about its pivot 41, the strip guide 13, due to the fact that itr is held down ofthe bell-crank lever 59 to a finger-piece 111' on thelever 11, said finger-piece being engaged by an ad usting screw67. An adgusting screw 69, threaded through the upper part of the bell-crank lever 59 abuts against the bracket a3; and these two screws furnishmeans for HClJUSlZlDg the lever 11 to brlng 1ts operat ve portion into proper position.

Before being operated upon by the machine it will be understood that the piping ;str1p or the margin of the shoe part-or both-have been coated with cement. The free. end of-a suitably. mounted spool of piping is led through the tube 17, through the channel 15.

in the piping guide 13 and'into-the field of action ofthe hammer and anvil.

191 and the material, for example a shoe part,

placed, display side down, with its edgeagainst the edge guide 9. The. piping guideis then released, andthe machine started whereby the. pipingwill be applied to the- At-theshoe partinthe desired manner; end of theoperation the piping is severed leaving a portion of 'th'e piping between the hammer and the anvil.

Although-the invention has been set forth as embodied in a particularmachine, it should:

be understood thatthe invention is notlimited-inthescope of its application to the particular machine which has been shown and described.
